The chicken HPRT gene: a counter selectable marker for the DT40 cell line

Nucleic Acids Res. 1999 May 1;27(9):1966-9. doi: 10.1093/nar/27.9.1966.


We describe the cloning, characterisation and chromosomal mapping of the chicken hprt gene together with the construction of two counter selectable hprt-/- DT40 derived cell lines. One of these cell lines contains a stably integrated gene encoding a conditionally active cre recombinase and thus allows efficient manipulation of targeted loci by site-specific recombination. These cell lines will enhance the utility of the hyper-recombinogenic DT40 cell line as a system for the genetic analysis of cell autonomous functions in vertebrates and as a tool for mammalian chromosome engineering.
